Though the GTX has faster core speed, the thing to look for on Nvidia side are the Processor cores with the few exceptions: 460:336PC VS 465:352PC, but the memory bandwidth and higher clock speed combined with better or more efficient power use of the 1gb GTX 460 gives them an edge over the 465. And the 480-480pc vs 570-480pc, which because of the weaker mosfets on the 570 I would pick the more energy hungry 480, just to get the extra headroom when ocing the card.Edited by cook - 4/15/11 at 1:52pm
